Edit: turns out I'd left it unpublished for a reason, the sample code

him for testing my broken code!
I've removed the broken code from the article below.

I'm not sure how many tools make use of this information, but at
the very least search.cpan.org
parses the information and displays it nicely as part of the distribution
meta-information on the distro's main page.
